SiriusXM Kicks off New Phase as an Independent Public Company

https://ih.advfn.com/stock-market/NASDAQ/sirius-xm-SIRI/stock-news/94521552/form-8-k-current-report

Lliberty shares have always traded at a discount, likely becuase you never got the divi. However, the merger is tax free to Liberty holders. So the gain you get from Liberty to SIRI shares will be exempt because LSXM owns those shares.

It's the reason for the merger rolling all ownership interest back into SIRI itself. It's going to be it's own fully owned company again without a major holder hampering it. Sept 9th all shares become freely tradeable with share restructuring including the Authorized Amount

New Auth: 900,000,000
New Outstanding: 360,000,000 +/-

LSXMA is trading at 22.60, SIRI at 3.93. 3.93 * 8.3 = $32.62. Can someone explain the difference, LSXMA is trading at 44% discount ???

The new batch of FTDs are insane. This week's options volume is stupid high. Short exempts are building. Rate to borrow is at 177%. SIRI could be the next big squeeze!!!

Go Siri!!!
Glad to see it finally moving back up!

SIRI...BREAKING THE.4.11 TRIGGER

SIRI...BREAKING 4 BUCKS

SIRI 4 BUCKS COMING Fast then 4.11

SIRI..READY FOR 4 BUCKS

Are we going back to eight dollars?

The next big technical target could be $4 for SIRI stock

Short Squeeze

SIRI....MASSIVE VOLUME....153 MILLION SHORT

Do your own DD sir

WHO IS THAT

Zack Morris is KING

SIRI...BOTTOM SWING PLAY

Why do you think there has been such a huge increase in volume over the last month? Before June, ADV was like 25 mil. Last 10 day volume was like 83m and June 21st had like 300m volume. I'm thinking we are about to see lots of volatility both before and after ER

Also, keep in mind they will have reduced shares outstanding to 10% current from aprox 3.8B i think falling 90% to 380,000,000 with a cap of 900,000,000 allowable. That's opportunity for dilution in the future should siri need the cash to repay dept or simply choose to issue out those shares allowing us to pay off that debt in return for what will likely be a niicer divi and hopeful improving value.

Point is, i see immediate consequences where if you may want that investment more liquid it may get dried to clay for a bit.

i do believe i'm going to wait till the reorganization before i buy back into this. i had shares purchased at 2.5x and unloaded yesterday after i saw the revamp to the reorganization. i think it's got huge potential coming as a company (that i subscribe to) but i see to much uncertainty for the market price of the company. Even if this rebounds to 3 or 4. It's not being reported on that this is going to be a reverse split in reality. Every one i've seen has led to a decline in the immediate aftermath as investors and traders wake up to see share reduction and high value.

I believe it messes with the human mind and the panic and sell off when it down turns out of irrational fear. So i'm waiting to see if a hopeful $30 stock goes on sale for lets say $18. That's the equivalent of packing shares at 1.80 today.

Go SIRI the company, be wary your risk and purchase price today.
Only my opinions.

Filings today, it's a reverse split coming with the (split-co). Auth shares appears capped at 905M.

Liberty Media and SiriusXM Announce Transaction to Simplify Ownership Structure of SiriusXM (12/12/23)


Liberty SiriusXM Tracking Stock Group Will Combine with SiriusXM and Form a New Public Company

Transaction Builds on SiriusXM's Durable Foundation and Positions Company to Drive Growth and Create Stockholder Value

Liberty and SiriusXM to Host Conference Call Today at 8:30 AM ET

ENGLEWOOD, Colo. and NEW YORK, Dec. 12, 2023 /PRNewswire/ -- Liberty Media Corporation ("Liberty Media" or "Liberty") (NASDAQ: LSXMA, LSXMB, LSXMK, FWONA, FWONK, LLYVA, LLYVK) and Sirius XM Holdings Inc. (NASDAQ: SIRI) ("SiriusXM" or the "Company"), the leading audio entertainment company in North America, today announced that they have entered into definitive agreements whereby Liberty Media's Liberty SiriusXM tracking stock group (NASDAQ: LSXMA, LSXMB and LSXMK) (collectively "LSXM"), will be combined with SiriusXM to create a new public company ("New SiriusXM"), which will continue to operate under the SiriusXM name and brand. New SiriusXM will have a single outstanding series of common stock and is expected to continue to be traded on the Nasdaq Global Select Market under the ticker symbol "SIRI".



"We have reached an important milestone in Liberty's ownership of SiriusXM. This combination will create value for all stockholders by eliminating the tracking stock structure, enhancing liquidity and allowing former LSXM stockholders to participate directly in the ongoing performance of SiriusXM," said Greg Maffei, Liberty President & CEO. "SiriusXM commands the largest paid share-of-ear in the car and has proven itself as an incredibly successful and profitable business. We are confident SiriusXM will continue to create value by building on its resilient business model to execute its strategic initiatives. We look forward to remaining meaningfully involved in the business and significant stockholders."

"We are pleased that the Special Committee of our Board of Directors has reached this agreement with Liberty Media, which will allow SiriusXM to enter its next phase of value creation," said Jennifer Witz, Chief Executive Officer of SiriusXM. "In a highly fragmented audio entertainment industry, SiriusXM has differentiated itself as the leading audio entertainment provider by creating an experience centered on our high-quality, premium, human curated radio that is more relevant than ever. In doing so, we have built a profitable business that is poised for continued success. With our strong foundation and as we roll out our next generation platform, we are transforming SiriusXM to drive long-term growth and stockholder value creation."

"The Special Committee of the SiriusXM Board of Directors, along with our independent advisors, has carefully and diligently evaluated Liberty Media's proposal and negotiated this transaction. We believe that the agreement we reached with Liberty Media is in the best interests of the Company and its stockholders," said Eddy Hartenstein, member of the Special Committee and Lead Independent Director of the SiriusXM Board. "With this transaction, SiriusXM will be well positioned to continue creating value for stockholders."

Transaction Benefits

The transaction will result in New SiriusXM being an independent public company, with no majority stockholder, a single class of shares and a board comprising a majority of independent directors.

New SiriusXM will have a simplified ownership structure and benefit from greater strategic flexibility and independence. It also provides New SiriusXM with access to a broader investor base and expanded opportunities for index inclusion. The additional float provided by the transaction is also expected to improve trading liquidity for New SiriusXM stockholders.

The transaction offers all stockholders the opportunity to participate directly in the long-term potential of the leading audio-entertainment company in North America.

Transaction Details

Under the terms of the transaction, Liberty will separate LSXM by means of a redemptive split-off of a new subsidiary of Liberty ("SplitCo"), which will hold its shares of SiriusXM and approximately $1.7 billion of estimated attributed net liabilities. Such net liabilities include LSXM's net debt (3.75% LSXMA convertible notes due 2028, 2.75% SIRI exchangeable bonds due 2049 and SIRI margin loan, net of corporate cash)1, as well as other liabilities for transaction fees and expenses, financing fees, litigation related liabilities and other corporate adjustments. In the split-off, holders of each series of LSXM common stock will receive a number of shares of SplitCo stock equal to the Exchange Ratio, calculated as described below, such that LSXM stockholders receive 1 share of New SiriusXM for each share of SiriusXM previously held at LSXM, adjusted for LSXM net liabilities. A wholly owned subsidiary of SplitCo will then merge with SiriusXM, and existing SiriusXM stockholders (other than Liberty Media) will receive 1:1 shares of SplitCo, which will become New SiriusXM. The transaction is intended to be tax-free to LSXM stockholders (except with respect to any cash received in lieu of fractional shares) and SiriusXM stockholders.

The Exchange Ratio will be calculated based on (i) the number of shares of SiriusXM held by Liberty, reduced by a net liabilities share adjustment (the "Net Liabilities Share Adjustment"), divided by (ii) the number of adjusted fully diluted shares of LSXM.

Liberty Media currently holds 3,205.8 million shares of SiriusXM attributed to LSXM. The Net Liabilities Share Adjustment to the Exchange Ratio will be determined as the amount of assumed LSXM net debt (excluding the 3.75% LSXMA convertible notes due 2028), with additional adjustments for transaction fees and expenses, financing fees, litigation related liabilities and other corporate adjustments, divided by the SiriusXM share price of $4.23, which represents the average of the SiriusXM daily volume-weighted average prices over the 20 consecutive trading days ending September 25, 2023, the day before Liberty filed a 13D relating to a transaction.

The adjusted fully diluted shares of LSXM will be calculated based on outstanding LSXM shares at closing, including the dilutive impact of shares underlying the 3.75% LSXMA convertible notes due 2028 and the dilutive impact of equity awards.

If the Net Liabilities Share Adjustment and the adjusted fully diluted shares of LSXM were calculated as of June 30, 2024, the Exchange Ratio is estimated to be approximately 8.4 shares in New SiriusXM for each share of LSXM held.

Pro forma for the transaction, and assuming the adjustment described above, at June 30, 2024, there will be approximately 3,392 million basic shares outstanding of New SiriusXM, of which former LSXM stockholders will own approximately 81% of New SiriusXM, with the SiriusXM minority stockholders owning the remaining 19%.

New SiriusXM will remain committed to the business' long-term target leverage ratio of low-to-mid 3x adjusted EBITDA.

SiriusXM has secured committed financing with availability of $1.1 billion from Morgan Stanley, Bank of America and J.P. Morgan, the net proceeds of which may be used to refinance Liberty Media's 2.75% Exchangeable Notes due 2049 and the existing Liberty Media margin loan secured by SiriusXM's common stock.

The transaction has been unanimously approved by Liberty's Board, the SiriusXM Special Committee and SiriusXM's Board of Directors. Greg Maffei is expected to be Chairman of the Board of New SiriusXM. The transaction is expected to be completed early in the third quarter of 2024, subject to approval by a majority of the aggregate voting power of the shares of Liberty SiriusXM common stock present, whether in-person or by proxy, at a stockholder meeting, the receipt by Liberty Media and New SiriusXM of tax opinions from their respective tax counsel, as well as the receipt of required regulatory approvals and the satisfaction of other customary closing conditions. Certain trusts affiliated with John Malone, the Chairman of Liberty Media, have entered into a voting agreement pursuant to which they have committed to vote their shares of LSXM in favor of the transaction. A subsidiary of Liberty Media owning a majority of the outstanding shares of SiriusXM has delivered a written consent approving the transaction on behalf of SiriusXM stockholders. The transaction will not result in any changes to the Liberty Formula One tracking stock group or the Liberty Live tracking stock group.

Sirius Stock Rises on Short Squeeze as Liberty Media Arbitrage Backfires -- Barrons.com

4:45 pm ET July 19, 2023 (Dow Jones) Print
Andrew Bary

An apparent short squeeze in SiriusXM, which has the highest ratio of short interest to its publicly available float among companies in the Russell1000 index, appears to be driving up the stock of the satellite radio operator.

SiriusXM (Ticker SIRI) is up 0.4% Wednesday to $5.31 after gaining 7% Tuesday. The stock has risen 25% in the past month.

"There has been a huge rally in the most shorted stocks in the last six weeks," says Jeff Wlodarczak, an analyst with Pivotal Research Group. He says SiriusXM has been one of the beneficiaries.

The rally in SiriusXM has stung investors who have a popular spread trade that involves a long position in LIberty SiriusXM Group (LSXMA, LSXMK), a tracking stock for Liberty Media, and a short position in Sirius.

In the past month, the Sirius/Liberty Sirius XM arbitrage trade has hurt investors with Sirius rising 35% and Liberty Sirius XM gaining just 12%. Liberty SiriusXM's nonvoting "K" shares (LSXMK) are up 0.4% Wednesday to $34.81.

The discount of LIberty SiriusXM relative to Sirius hit around 45% Tuesday, compared with 35% in June.

SiriusXM has a thin float -- or amount of stock available for trading. That's because Liberty Media, controlled by mogul John Malone, holds 3.2 billion of its shares, or a roughly 83% stake. The recent short interest in SiriusXM of 219 million shares represents about a third of the public float of around 700 million, Bloomberg data show.

Other companies with high short interest ratios in the Russell 1000 also have rallied lately including Wayfair (Ticker W), Coinbase Global (COIN), and QuantumScape (QS).
